Authorities have focused efforts on tackling organised crime and immigration offences in Great Yarmouth.

The Security Industry Authority (SIA) targeted the town as part of a nationwide coordinated operation.

On October 31 the action day, organised by the Home Office, involved turning up at construction sites where organised crime was linked to security company staff.

It also aimed at tackling security licence fraud, labour exploitation and money laundering.

Pete Easterbrook, head of criminal enforcement at the SIA said:  “This operation was a result of intelligence originating from within the private security industry which was developed and analysed by our intelligence team and involved collaboration by our criminal enforcement and compliance and inspections teams.

"Thanks to these combined efforts we have struck a significant blow against those seeking to use the private security industry as a vehicle for criminality including the exploitation of vulnerable people."

Across the 11 areas that were targeted nationally, two arrests came for people overstaying their visas in Yeovil and Ilkeston.

Eddy Montgomery at the Home Office said: "Exploitation of illegal workers within the UK construction industry is on the rise, with rogue employers showing complete disregard to the safety and rights of legal foreign workers who contribute significantly to this sector."
